Help deciphering enginey things - DET3 launch control setup!

[Akagi]

Hi guys,

So my Corolla has an ECUMaster DET3 wired in, and I would like to set up the launch control. Partly "just cos" and partly because I think it would be fun to use at the next Santa Pod meet we do.

The settings available to me are:

Parameters:

Activation input – what input used for activating the launch control function. For extra analog input table switch input must be configured as “Use as launch control”

Activation RPM – engine speed which the ignition retardation and the fuel mixture enrichment takes place

Cut off RPM – engine speed when the ignition will be cut off,

Ignition retard – ignition retard angle during the staring procedure

Fuel Enrichment – value added to the current Analog Out value.

Enable VSS control – enable vehicle speed sensor (VSS) control over launch control

VSS Limit – frequency (in Hz) of Frequency In input, above launch control function will be automatically turned off

I have no idea what to do with these settings...

The input will be a toggle switch... And I understand that the cut-off RPM will be the RPM it holds for the launch, but thats all I know!

Guessing I ignore the last two options, and I know what to put for the first one, and the cut-off I think I'll have as about 3250RPM, but what about:

Activation RPM
Ignition retard
Fuel enrichment

Tomorrow on ACME's Adventures... "My clutch is slipping, bought lemon"

The Corolla is faultless honestly. Thrash it around all over the place and it has yet to miss a beat. Everything works. Probably the least lemony car I've owned.

I'll poke about with the DET3 this weekend. I think launch has been enabled at some point in the past, so if I'm lucky the settings will still be in there...

The child in me is looking forward to having a capped toggle switch next to the gearstick. (I have a spare gearstick surround so I'll drill a hole for a switch in the worse of the two)

"My cat is destroyed because the launch control dumps fuel into it"

I wonder how the millions of cars which have launch control manage...

Looking forward to some fireworks videos

I'm not planning on increasing the fuel, I just want to make it work

Like this:

Not this:

Anyway as above, I'm not increasing the fuelling. I dont want flames.

 

[Akagi]

Launch control on the typical car cuts fuel, 2 step keeps fuel going in to spool turbos. Yours has a setting for fuel change... I'm fairly sure it'll dump all that fuel straight out the exhaust.. thus destroying your cat.

OK so I'll set that value to 0? So complicated............

Ask on corolla club uk, I'm sure someone on there will know.

In the Facebook group they're all chavs that lick Sam Nadeems arse ring (the guy who sold me that Celica), I left that group a long time ago.

I might join the forum and see if the people there are more helpful though, taa.

Fuel ENRICHMENT...

Hey... it's your car, I'll await the fix it thread for drive shafts, gearboxes, clutches and cats

So I'll set it TO ZERO...

It doesn't have enough power to break any of those things.

I've posted on the forums. Seems I already had an account. Wrote a long post explaining an issue in detail, and nobody replied for 2 days. So I don't hold out too much hope

can i have your email to ask you something about your miata and DET3, please ?
Thank you!

He's using a Megasquirt standalone I believe.

And I don't have my DET3 anymore. Sorry!
